T all whim/0 it y concern: circular hub of the wheel or brush provided Beitknown that I, HENRY C. TOPP, acitizen with the central hole a for arranging it upon of the United States, residing at Newark, in an arbor. Said disk or hub a is provided in the county of Essex and State of New Jersey, its periphery with an annular groove or re- 55 have invented certain new and useful Irncess a formed by the two parallel shoulders provements in Brushes; and I do hereby de- (L as will be clearly seen from an inspection clare the following to be a full, clear, and eX- of Figs. 2, 3, and 4.

In said annular groove or re 65 I 5 circular brushes, such as are used on lathes, cess a I have arranged a cushioning material to produce upon the article held against it b, which maybe of soft and elastic rubber or What is commonly termed a satin finish or any other similar material to produce a cushscratch-brush finish; and the invention ioning ell'ect.

Here the wire struction of circular brush, and Fig. 2 is a verbunches are secured in place in the usual 85 3 5 tical section of the same.

It will be seen that in my novel construction of rotary brush the hub and its annular shoulders are all made in one integral piece, and the cushioning material I) is forced between said shoulders, where it is removably but operatively held and can be quickly detached when the wire bristles have become worn and can be replaced by a new pieceof cushioning material provided with bristles without necessitating the separation of the several parts of the hub, as in the constructions of brushes of this character now made. By this means I have devised a cheaper and more satisfactory construction, and there is no danger of the screws becoming loose and detached when the brush is being rapidly revolved on its arbor.

In rotary brushes when made in the manner hereinabove described it has been practically demonstrated that the soft and elastic cushioning material 1), surrounding the hub of the brush, allows of a vibratory action of each separate bunch of wires at the point where it passes into said cushion-support, and the wire bunches upon being revolved against a hard substance will not break at their point of support.

It will be clearly understood that these brushes can be put to different uses, such as polishing metal ware of any description to produce satin-finished? surfaces thereon, but they may also be used to clean castings and for many other purposes.

Having thus described 1nyinventio11,wl1at I claim is- 1.. A circular brush, comprising therein, a

solid hub, at, having annular shoulders on its cylindrical surface forming a groove or recess, a cushioning material I), forced in said groove or recess, and removably held therein by friction, and wire bunches c in said cushioning material, substantially as and for the purposes set forth.

2. A circular brush, comprising therein, a solid hub, a, having annular shoulders on its cylindrical surface forming a groove or recess (1 and holes or perforations a a cushioning material I), forced in said groove or recess, and removably held therein by friction, and having holes Z) corresponding to the holes a in said hub a, and wire bunches extending through said holes I) and fastened in said holes a, substantially as and for the purposes Set forth.

3. A circular brush, comprising therein, a hub, as a, having an annular groove or recess (4 and holes or perforations a, openings or and a on the opposite sides of said hub, a cushioning material I), in said groove or recess, and having holes 1) corresponding to the holes (0 in said hub a, wire bunches extending through said holes I) and fastened in said holes a, and soft-metal layers d in said openings a and a, all arranged, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereunto set my hand this 14th day of April, 1896.
